To troubleshoot LG dishwasher door problems, remove any debris build up around the door vent, check for any damage to the door hinges, confirm that the door catch is aligned properly, deactivate the child lock feature, and remove any obstructions between the door and interior.
If your LG dishwasher keeps beeping, check to ensure the door is shut up tight. In most cases, the dishwasher will emit beeps when the door becomes unlocked during a cycle. This helps alert you that the door needs to be closed and sealed to prevent water from running out of the machine.
If your LG dishwasher is flashing lights, pay close attention to the sequence and the symbols of the lights. This could be an indication that the rinse aid needs to be refilled, the cycle has paused, or that the salt in the appliance needs to be replenished, among other possibilities.
To reset an LG dishwasher, there is not a designated reset button on these appliances, but you manually reset the device by discontinuing power to the unit for 10 seconds. Once this time has passed, restore power to the dishwasher and run an empty cycle to complete the reset.
An issue with an LG dishwasher not drying can often be traced to a user error. If the dishes are not loaded properly or if they are overloaded, then the dishwasher will not be able to dry them. Otherwise, it could be an issue with the heating element.
For the most part, a problem with an LG dishwasher not draining can be traced to issues with the drain hose. If the hose is kinked or has become clogged with food particles, the dishwasher will not drain and all of the water will remain in the bottom of the machine.
